Buying Guide: Key Purchase Considerations
When selecting yellow Four O’Clock seeds, consider climate, space, and how you want them to function in your garden. If you want a container or short border, choose compact varieties around 12-36 inches tall. For larger borders or hedges, taller options that spread gradually work best. Sun exposure is important; these plants typically prefer full sun to partial shade, with late-afternoon bloom windows that suit evening gardens. Seed longevity and reseeding tendencies vary by brand, so consider whether you want a self-sowing plant or a more controlled annual that requires replanting each season.
Seed origin and growth habit can influence performance. Some seeds are labeled as perennials in warmer zones and annuals in cooler regions, so check your USDA zone and expected winter conditions. For fragrance lovers, scented blooms add an extra layer of garden charm, especially when paired with night-pollinating visitors. If you’re planting in borders or hedges, think about spacing—most options thrive with 12-36 inch spacing to avoid crowding and ensure good air circulation.
